Struct Measurement

pub struct Measurement<'a> { /* private fields */ }

Data container for a DHT sensor measurement that contains either an error or data.

use dht_logger::{Measurement, SensorData};
// Example test data
let error = "test";
let data = SensorData {
    temperature: 0.0,
    humidity: 0.0,
    heat_index: 0.0,
};

// Create a measurement containing an error
let measurement = Measurement::new(None, Some(error));
assert!(measurement.get_data().is_none());
assert!(measurement.get_error().is_some());
assert_eq!(measurement.get_error().unwrap(), error);

// Create a measurement containing data
let measurement = Measurement::new(Some(data), None);
assert!(measurement.get_data().is_some());
assert!(measurement.get_error().is_none());
assert_eq!(measurement.get_data().unwrap(), data);

Implementations

impl<'a> Measurement<'a>

pub fn new(data: Option<SensorData>, error: Option<&'a str>) -> Measurement<'_>

Create a new measurement of a DHT sensor.

Args:

• data: Sensor data from one DHT sensor.
• error: Error indicating a failure to read a DHT sensor.

pub fn get_data(&self) -> Option<SensorData>

Get the data contained by the measurement, if it exists.

pub fn get_error(&self) -> Option<&'a str>

Get the error contained by the measurement, if it exists.

pub fn has_data(&self) -> bool

Check if the measurement has data.

pub fn has_error(&self) -> bool

Check if the measurement has an error.
